What Girls & Guys Said

Depends on who I get along with better. There are other things about the personality which would help me make the choice, but typically, smarter people have those traits, so it's likely for my choice to be the smarter one.

If guys were honest, they would always pick the attractive. I would say, however, that once my penis stops making decisions for me in my 50s or 60s, I will look to settle with a wicked smart, unattractive woman to spend my twilight years with in the pursuit of knowledge together.

Not really. Being attractive is definitely a plus, but that won't last you forever if you're thinking about things for the long run. If you're not so serious about your relationship, then you'll probably go for the more attractive one because you're mostly just thinking about fun and playing the lottery for the long run. Those kind of people would leave you with the first chance of getting a better deal.
